PROBLEM TO BE SOLVED: To flexibly change the content of channel selection with simple constitution by dividing a part or all channels into partial channels and selecting the divided channels. SOLUTION: A part or all the channels are divided into the partial channels and the divided channels are selected. In a picture information transmission-side device, a highly precise picture is inputted to a multiplex circuit 710 through a distribution circuit 700, is multiplexed together with a standard picture and is inputted to an interface circuit 720 by a station transmission line 10, for example. The highly precise picture is divided into the partial channels of the respective channels, for example, are added with address pulses and stuff pulses in the multiplex circuit 710, are phase-adjusted, are interleaved/multiplexed by the multiplex circuit 710 and are transmitted to a transmission-side attendant circuit 720. The address pulse and the stuff pulse are added to the standard picture as they are. |
